Title: **William M. Hann: Innovator in Corrosion Inhibition and Oilfield Solutions**
Introduction
William M. Hann, based in Gwynedd, PA, is a prolific inventor with a significant portfolio of 11 patents. His work primarily focuses on developing innovative solutions for corrosion inhibition and scale control in challenging environments, particularly within the petroleum industry.
Latest Patents
Among his latest contributions are two groundbreaking patents. The first patent, titled "Corrosion Inhibiting Compositions," introduces a new class of polymeric compositions featuring pendant heterocyclic groups. These compositions serve as remarkably effective corrosion inhibitors for copper, forming a protective barrier on metallic components in aqueous systems. Notably, these polymers maintain their effectiveness over a wide pH range and demonstrate resistance to both oxidizing biocides and corrosive agents.
The second patent, "Method for Metal Sulfate Scale Control in Harsh Oilfield Conditions," presents a method to inhibit barium sulfate precipitation in low pH aqueous fluids found in underground petroleum-bearing formations. This involves the addition of a specific polymer composed of 5-35 weight percent sulfonic acid monomer units and 65-95 weight percent carboxylic acid monomer units. The preferred polymer compositions are particularly effective in conditions with high sulfate ion and barium ion concentrations, especially at very low pH levels, such as 5.5 or lower.
